I have a directory Source with some files in it, which I would like to copy to a folder Destination. Destination may exist, and it may have files in it already. Any files with the same name as those in Source should be overwritten.

Then the first line creates the folder .\Destination and copies .\Source into it, which is what I'd like to repeat for the next time. However, the second line copies .\Source into the new .\Destination folder (creating .\Destination\Source) instead, then the third line overwrites .\Destination\Source again.

How can I make it act like in the first case all the time? That is, overwrite .\Destination instead of copying into it?
